The anti-epileptic activity of CBD and CBDV is thought to be modulated by their effects on transient receptor potential cation channel subfamily V member 1 (TRPV1), also known as the capsaicin receptor, which is part of a large family of ion channels that are involved in the onset and progression of several types of epilepsy. CBD and CBDV have been shown to dose-dependently activate and then desensitize TRPV1 as well as TRPV2 and TRPA1 channels. Desensitization of these ion channels is a potential mechanism by which these molecules cause a reduction of neuronal hyperexcitability that contributes to epileptic activity and seizures. CBDV has also been shown to inhibit the activity of diacylglycerol (DAG) lipase-α, the primary synthetic enzyme of the endocannabinoid, 2-arachidonoylglycerol (2-AG). The clinical implications of this are unclear however, as this interaction has not been shown to affect CBDV's anticonvulsant activity.

Like Δ9-THC, CBDV has low water solubility and poor oral bioavailability (~6% in humans), making oral administration an unfavourable method of delivery. Despite this, CBDV has relatively rapid absorption with peak concentrations seen around 2 h after oral administration in animal pharmacokinetic studies. Orally administered CBDV in mice was found to have a plasma Cmax of 0.47ug/mL and Tmax of 30 minutes, and a brain Cmax of 0.94ug/mL and Tmax of 60 minutes.

Due to its lipophilicity, CBDV has been shown to cross the blood brain barrier.
